In Western Polynesia we obtained 53 species, 18 of which 

 did not occur to our notice in the Eastern groups. 



Eastern Polynesia yielded 56 species, 20 of Vv'hich we did not 

 observe in the Western Islands. 



Owing to the almost total absence of coral reefs at the Mar- 

 quesas, we find but few species, though a more careful exploration 

 will undoubtedly add some, but not many more, to the 13 re- 

 corded from that group. 



1. C. (Aricia) annulus, Lin. This common and well-known 



species occurs on reefs and weedy bottom in shallow water. 

 Though plentiful in all the Western groups, it did not occur 

 to our notice in any part of Eastern Polynesia, where it is 

 represented by the closely allied C. ohvelata. 



2. C. (Aricia) Arabica, Lin. Common under dead coral on 



reefs at the Viti, Tonga, and Samoa Islands, and more rare 

 at the Kingsmill and CaroHne groups. At the Society and 

 Paumotu Islands we obtained several examples, which were 

 larger, more depressed, the teeth coarser, the aperture more 

 open, and the round spots more conspicuous than in Western 

 specimens.
